Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
What 2 factors determine biodiversity?
Biotic, abiotic and human influences are all factors that affect biodiversity in an ecosystem.
What are all the factors affecting biodiversity?
The numerous factors are responsible for the loss of Biodiversity (Figure 1) such as pollution, habitat loss, hunting, introduction of invasive species, overexploitation of preferred species, climate change, and natural disasters. Figure 1: The causes of Biodiversity loss.
What are the three factors of biodiversity?
Biodiversity is an abbreviation for biological diversity. It generally means the ‘diversity of flora and fauna (plants and animals)’ (IB definition). It has three factors, ecosystem, species and genetics.
What are the major factors affecting biodiversity today?
Major threats to biodiversity are:
- Habitat destruction/Deforestation.
- Introduced and invasive species.
- Genetic pollution.
- Over exploitation.
- Climate change.
- Human over-population.
What two factors influence the biodiversity of an island?
The Equilibrium Model of Island Biogeography (EMIB) states that, other things being equal, area and geographic isolation are the two main factors determining extinction and immigration rates, which in turn regulate the level of species richness that is reached at a dynamic equilibrium , .
What factors have influence over biodiversity both positive and negative?
Human interaction within ecosystems can have both positive and negative impacts on the levels of biodiversity. The impact of an increase in the human population , including increased waste, deforestation , peat bog destruction and global warming has been to reduce biodiversity .
What is biodiversity and its 3 types?
Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).
What are the 4 types of biodiversity?
Four Types of Biodiversity
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. …
- Ecosystem Diversity. …
- Functional Diversity.
What factors affect biodiversity Why do wetlands have a high level of biodiversity?
Wetlands have a high level of biodiversity because of the amount of resources available. The high levels of accessible water, nutrient levels, and primary productivity allow for a large number and variety of organisms at the base of the food web.
